Since the Foster Home is only available in Goldenrod, I'd be cool with Riku maybe opening the Training Center as a second drop off site. That's really your call, though-- just thought I'd offer it up, since he's been using the TC to house some dropped Pokémon already.

Also, thanks for the updates! There are some Pokémon I've wanted to put up for adoption for quite some time, so I'll go ahead and toss them up.
